Given a string s consists of upper/lower-case alphabets and empty space characters ' '
, return the length of last word in the string.
If the last word does not exist, return 0.
Note: A word is defined as a character sequence consists of non-space characters only.
For example,
Given s = "Hello World"
,
return 5
.
class Solution
{
public:
int lengthOfLastWord(string s)
{
int n=s.size()-1;
int res(0);
while(n>0)
{
if(s[n]==' ')
n--;
else
break;
}
while(n>0)
{
if(s[n]==' ')
break;
else
res++;
n--;
}
return res;
}
};
